Thyroid hormone is crucial for metabolism and development. Cellular thyroid hormone homeostasis requires adequate function of (i) thyroid hormone transporter proteins, (ii) deiodinating enzymes and (iii) nuclear receptors. Thyroid hormone transporters are crucial for cellular uptake of T3 and T4. Over the last years, a number of thyroid hormone transporters have been identified and their physiological relevance has been established. The most well-studied example is MCT8 defici...

Central hypothyroidism can be best defined as lower than desirable thyroid hormone production and secretion because of insufficient stimulation of a normal thyroid gland by a defective pituitary or hypothalamus, resulting in a too low plasma or serum (free) thyroxine (FT4) concentration accompanied by a more or less normal thyrotropin (TSH) concentration. Central hypothyroidism can occur isolated or as part of multiple pituitary hormone deficiency and can be a congenital or ac...

Pediatric differentiated thyroid carcinoma (DTC), which includes papillary (PTC) and follicular thyroid carcinoma (FTC), has an excellent prognosis (15-year survival rates >95%). The initial treatment in children generally consists of a (near) total thyroidectomy, followed by ablation therapy with radioiodine (131-I), nowadays, the latter often depends on risk stratification. TSH suppressive therapy with thyroid hormone has for decades been administered during follow-up to...
